i know this has been asked before, and even by me. so i went to lake naci at the end of the summer and had a great time with family and friends. right now i use a 55ft rope behind my 2005 wakesetter vlx with full ballast, 2 250lb on each side in the back and 1 500lb in the center.i only have to cut out ten-fifteen feet to go w2w. right now i can gap the wake toeside, heelside, and switch toeside, and switch heelside. i went to lengthen my rope and bump up my speed from 21mph and 55ft to 22mph and 60ft. when i went in with my heelside edge i couldn't gap it which hurts after getting used to soft landings while i was going w2w. i am also 4'11" and 85lbs.

Take a little more speed into the wake, using the same technique as 55ft at 21 (progressive edge, standing tall at the top, blah blah, you know the rest). Also, "clear" the wake is the term used more often, rather than "gap". May help you get your point across better. Best of luck, if that doesn't work, repost, I'm sure we can get this figured out no problem.
